in the county of Lorain and State of Ohio, haveinvented new and usefulImprovements in Shoe-Heels, of-which the following s a 1 specification.

This invention relates to shoe heels and aims to provide a heelconstructed of rubber or other compressible material which may-be eitherpermanently or detachably secured to a shoe. Y

The primary object of the invention is to provide a heel of thischaracter with an auxiliary cushioning means in the form of -a raisedportio extending. beyond the tread surface of th? out or provided with acavity upon the upper surface at the rear of the raised portion topermit'the latter to yield under, pressure,

.aplurality of radially disp sed ribs extend ing. from the side wall ofthe cavity and normally spaced from the heel the shoe to providea stopto yield1nglylim1t the inward movement of the auxiliary cushion.

Other objects and-advantages of the invention will appear as thefollowin description is. read in connection with t e accompanyingdrawings, iif which Figure 1 is a perspective view of a shoe heelconstructed inaccordance with the present invention;

concaved as showniand is further provided with a cavity or depressionlapreffesrl'lably of a o 1s cav circular form. The lower w ity extendsbeyond the lower or tread'surthe lower Wall of the cavity an heel, theheel being hollowed ort on of" forme face ofthe heel as shown at 14 torovide anauxiliary cushioning means-for t e heel. Disposedconcentrically withi'n the cavity 13 is a rin 15, preferabl formedofrubber and ma e integral wit the lower wall of the cavity, the uppersurface or edge of. this ring terminating short of the upper surface 12of the heel. Connecting the ring and the inner wall of the cavity are aplurality of radially disposed ribs 16, the upper edge of these ribsbeing slightly curved so as to be flush withboth the upper edge of therin 15 and the upper surface 12 of the bee These ribs form astrengthenin means for act in conjunction with the ring 15 to limitthee-inward movement of the wall under pressure by contact with the heelportion of the shoe. The heel is preferably provided with a lurality ofdepressions 17 disposed aroun' or adjacent its edge for the reception ofnails or suitable fastening devices by means of which it may be securedto the shoe.

In Figs. 3 and 4 there is illustrated means whereby the heel may bedetachably-secured to the shoe. In this form of the invention the heel10 is similar inconstruction' to the form. previously described, exceptthat it is V -'shapedgroove 18, which is adapted to receive a similarlyshaped tongue or flange 19 formed around the edge of a secnrin plate 20.This plate is preferably formed 0 metal and is provided witha pluralityof .apertures 21 for the passage of nails or other fasten- Y ingdevices'for the purpose of securing the plate in the heel-portion of the-shoe."In order to secure the heel against accidental around its edge with asubstantially displacement, the latter is rovided with a hook member 22which is. a apted to engage in a slot 23 formed in the plate 20:, One

edge of the slot 23 is provided with beveled surface 24' to provide acloser grip beneath :the hook. The hook member is formed of a strip ofmetal-having each of its ends bent substantially at right angles and inopposite directions, I one of -these ends 'fol' lfig the hook 22, whilethe other end has its edges flared outwardly to provide an anchor 25.

Openings 26 are formed in the hook member, so that when the lattefr isembedded in the heel as shown in Fig. ,5, the material will enter theopenin 26 and together with the anchor 25 secure y hold the said memberimposition.

The invention is susceptible of .various "in the upper surface thereof,a raised portion forming, the outer face of the lower wall of the cavityand extending beyond the 1 lower tread surface of the heel and a hollowcompressible element located within the cavity or depression, theupperend of said element terminating short of the upper edge of the cavity. g

2. A shoe heel formed of compressible material and having a cavity ordepression in the uppersurface thereof, a raised portion forming theouter face of the lower wall ofthe cavity and extending beyond the lowertread surface of the heel, a concentrically disposed ring located withinsaid depression or'ca'vity and terminating short of the upp edge of saidcavity and radially arrange ribs connecting the ring with the side wallof the cavity.

3. A shoe heel formed of compressible material and having a cavity ordepression in the upper surface thereof, a raised portion forming thelower wall of the cavity and extending beyond the lower tread surface ofthe heel and a hollow compressible stop located within the cavity ordepression, the upper end of the stop terminating short of the upperedge of the heel, and means for cognecting the cavity to a shoe.

- A shoe heel formed of compressible material and having a cavity ordepression in the upper surface thereof, a raised portion forming theouter face of the lower wall of the cavity and extending beyond thelower tread surface of the heel, a concentrically disposed ring locatedwithin said depression or cavity and radially arranged ribs con-.necting the ring with the side Wall of the cavity and terminating shortof the upper edge of said cavity and means for connecting the heel to ashoe.

5. A shoe heel formed of compressible material and having a cavity ordepression in the upper face thereof, a raised portion forming the outerface of the lower wall of the cavity and extending below the lower treadsurface of the heel, a plate secured to the heel portion of the shoe, anS-sh'aped member having one end embedded in the heel and its oppositeend extending to provide a hook for engagement with an opening in theplate and a flared portion formed in the embedded end of the hookmember. 6. A shoe heel formed of compressible material and having acavity or depression in the upper surface thereof, a raised portionforming 'the outer face .of the lower wall of the cavity and extendingbelow the 'ower or tread surface of the heel, a plate secured to theheel portion of the shoe, a

flange of substantial triangular cross section extending partiallyaround the marginal edges of the plate for engagement with a similarlyshaped groove in said heel and a stop located within the cavity andnormally spaced from the plate for contact with the latter to yieldinglylimit the inward movement of the lower wall.

7. A shoe heel formed of compressible material and provided with acavity or depression in its upper surface, a compressible raised portionforming the'outer face of the lower wall of the cavity and extendingbeyond the lower tread surface of the heel and arranged to be flexed toform a substantially flat tread, surface, and a stop within said cavityor depression.

In testimony whereof I aflix my signature.
